Fog machine
A fog machine is a device, used primarily in theatrical environments, which converts a water-based fluid into a dense smoke-like vapor. This generated "smoke" is perfectly safe to breathe, although individuals with breathing complications such as asthma may experience some irritation.
Fog machines are used many times to add eerie effects to the stage in plays such as Dracula, A Christmas Carol, and Macbeth. Fog machines are also frequently used in halloween displays such as haunted houses or forests. Because of recent (2003–2005) price changes and availability, fog machines can be seen on the doorsteps of everyday houses during the season of halloween.
